Answer 2

Solution :-

Here, A quadrilateral is given

The sum of three angles equal to thrice the fourth angle

Let the angle be a , b, c, d

According to the question,

a + b + c = 3d. ( 1 )

As we know that,

The sum of angles of a quadrilateral is 360°

Therefore,

a + b + c + d = 360°

From ( 1 )

3d + d = 360°

4d = 360°

d = 360° / 4

d = 90°

Hence, The fourth angle of quadrilateral is 90° $.$
